The purpose of this study is to explore other treatments for patients with superficial bladder cancer. The investigational medication to be studied is an enzyme called hyaluronidase, and it is a human recombinant form of the enzyme. An investigational medication is a medication or formulation of a medication that is not approved by the United States Food and Drug Administration for use in this country but it may be used in studies such as this one. The drug company name for this medication is Chemophase. Chemophase will be given in combination with mitomycin C. Mitomycin C will be given alone one time and then both drugs will be given together weekly for 5 weeks. Mitomycin C is an anti-tumor drug that is commonly used to treat superficial bladder cancer. Treatments are administered directly into the bladder. It is envisioned that Chemophase with mitomycin C may potentially increase the local penetration of mitomycin C into remaining cancer cells following surgery to treat superficial bladder cancer.
